Fingerprint Verification Design Enlists DSP Technology

The Fingerscan Biometric Embedded Module (BIO-EM), a fingerprint verification reference design, exploits the power of a TMS320VC5507 digital signal processor (DSP) from Texas Instruments. Authenticating users by capturing, converting, storing, and matching fingerprint images, the module is a complete, standalone design that includes two boards: a motherboard with the DSP, memory, USB port, and LEDs plus a daughtercard that hosts touch or sweep sensors from Fujitsu. The module is said to be easily customized and can operate in standalone mode. Price is $249 each/
